In January, this photo of a teary-eyed Song Ji-hyo embracing Song Joong-ki was going viral.

The onscreen chemistry between Song Joong-ki and his co-star Song Hye-kyo was breathtaking that the fans want them to get together in real life too. This even led to a new hashtag on social media sites: For long #SongSongCouple has been trending on Facebook, Instagram and Twitter.

Although the beautiful actress was spotted several times hanging out with her charming co-star, the duo has always denied speculations of real-life romantic involvement.
